Question
BUCK-BOOST CONVERTERS 7-12 In a buck-boost converter, consider all components to be ideal. Let Va be 8-40 V, V. = 15 V (regulated), f, = 20 kHz, and C = 470 µF. Calculate Lmin that will keep the converter operating in a continuous-conduction mode if P, 2 2 W. 7-13 In a buck-boost converter, V = 12 V, V, = 15 V, I, = 250 mA, L = 150 µH, C = 470 µF, and f. %3D 20 kHz. Calculate AV, (peak-peak). 7-14 Calculate the rms value of the ripple current in Problem 7-13 through the diode and, hence, through the capacitor.
